Multiplex Fun Jet

High
speed pusher Jet

Overview

I make models are able to fly
fast many time. Because high speed flight is one of my favorites. This
time, I try to
make lighter. Looking for heavy parts in standard setting, I found,
it's motor ! Original motor is
Himax HA
2825-2700. Weight is 135g + "connector about 4g". If choose Warp4 or
MEGA 15/16/x, its weight is about 75g. My choice is "Warp4 2T kv3880 +
APC S400
4.1x4.1" 430W input power. Pitch speed is approx 210km/h. The Fun Jet
is able to fly over 100mph, isn't it ?
After maiden flight, changed motor TURNIGY
2836-3200 & propeller APC S400 4.5x5.5. The motor is out
runner brushless and max input power 650w. However its setting power is
output 320W, pitch speed 210km/h. Is it enough ?

Assembly report

Same company product Micro Jet, its parts
quality is
much better, ex. under cover plastic sheet and linkage
parts. However Fun Jet parts are ordinary one. ELAPOR® is just
foam. I feel
Fun
Jet price is expensive comparing Chinese EPO and other foam Jet plane.
But motor mount is very very nice ! It is adjustable down/upper
thrust. Photo
